Sachsenroeder Gmbh Introduction Nature Technology iNNovatioN FuTure Hig H-tecH materials manufactured using natural fibres 2 iNNovatioN made by sachsenrÖder. _ guStav SaChSEnRödER invEntEd ContinuouS vulCanizEd fibRE. Innovation is the power to create something new. This capacity has a long history at Sachsenröder. Only a short while after establishing the company, Gustav-Heinrich Sachsenröder manufactured continuous vulcanized fibre at the beginning of the 20th century in a factory beside the river Wupper. He was the first to successfully use a sulphuric acid process. ® ® _ SavutEC and gESaduR in uSE all ovER thE WoRld. HigH-tecH materials HigH-tecH More innovations were to follow. In over 125 years of company history, a broad range of vulcanized fibre products now with the brand name SAVUTEC ® has been developed. These are used in a variety of industries and applications all over the world. The product line is complemented by high-density thermosetting plastics under the brand name GESADUR ®. _ ExPERiEnCE and REnEWablE RaW MatERialS. The development department constantly works on optimizing our high-yield products. sacHsenröder sacHsenröder The Sachsenröder company can rely on the technical competence and the vast experience of its employees and utilizes high-tech products one of the most important resources of our times in a precisely targeted way: renewable raw materials. Materials made by Sachsenröder are high-tech from nature – sustainable, pioneering and innovative by nature. savutec® tHe eXtreme natural fibre. The basic material for vulcanized fi bre products is cotton fi bres. They belong to the group of renewable raw mate- rials. The raw paper that is made out of the plant fi bres is then parchmentized and thus becomes the vulcanized fi bre SAVUTEC®. Sachsenröder manufactures SAVUTEC® in a variety of qualities, precisely tailored to the applica- tion in question. gesadur® tHe natural polymer. 60 % of GESADUR® consists of natural fi bre that Sachsen- röder uses for making a homogeneous polymer based on high-density thermosetting plastics. During the curing process its structure becomes extremely solid so that it can no longer be deformed. GESADUR® WN is a material of choice in the manufacture of support rollers in the wire stranding industry. 3 From plant Fibre to vulcanized F ibre. g Process N 01 Cotton plant 02 Seed capsule of the cotton flower tHe preliminary stage // raw paper. The basic material of the vulcanized fibre SAVUTEC® is cotton, and it is the cotton fibres that are processed or, more precisely, the 3-5mm long linter fibres. These consist of cellulose that is gained from the seed hair of the cotton flower. After the harvest, the cotton linters are mechanically cleaned, cooked and bleached. The paper ufacturi machine then forms the actual paper structure: For this purpose the cellulose is dissolved in water and made into a paper pulp. This pulp, which in the beginning consists of 99 % water, runs over an endless screed that dehydrates N the pulp step by step. The rolled up raw paper sheet is parchmentized at Sachsenröder.

For parchmentizing, one or several layers of raw paper are pulled through a bath with concentrated sulphuric acid, wrung out and subsequently washed out in several baths with decreasing concentration. The acid ensures that the fibres of the cotton tie together anew. »Hydrate cellulose« forms on the surface. The sulphuric acid serves as a catalyser which is washed out completely (neutral pH factor). Subsequently, the vulcanized fibre Savutec® is cured, rolled up and packaged. 06 Parchmentizing process 05 Raw paper sheets 5 savutec® rediscover proven material. ptional o ® can be made in can be made in _ PRovEn MatERial on a natuRal baSiS. ® Vulcanized fibre - the name originated from the vulcanization of natural rubber to make hard rubber which is a process similar to parchmentizing raw paper.

With SAVUTEC® Sachsenröder offers a vulcanized fibre of the highest quality and with savutec various qualities. The material properties are determined by the fibre quality and the set up of parchmentizing - tailored to any application. Upon request, SAVUTEC ® is also available in matching colours. _ ExPERtiSE and ExPERiEnCE. Vulcanized fibre has thus proved to be one of the most flexible materials that exist. However, its many possible variations can only be exploited if you have special knowledge and the corresponding experience. Sachsenröder provides this expertise - collected, expanded and refined since 1881.

SAVUTEC® is a strong, horn-like material that is very easily formed. The proprietary vulcanized fibre is hard, tough and wear-resistant. It convinces with its high mechanical strength and an extreme tear resistance. _ a vaRiEty of aPPliCationS. What you can do with SAVUTEC ® is no less impressive: The material can be worked by bending, embossing, punching, cutting, drilling, milling, grinding, planing and glueing. The with corrugation applications are equally varied. SAVUTEC ® is particularly suitable as a carrier for abrasives and ® ensures that wood veneers do not peel off.

SAVUTEC® SM/SMS forms the basis for corundum coating of abrasive disks that achieve a circumferential speed of 80 m/sec. This means high demands on the tensile and adhesive strength as well as on the thermal resistance of the material. No problem with SAVUTEC ® SM/SMS!

  • Parchment-Like Paper Using Water Hyacinth Pulp
    Philippine Journal of Science 141 (2): 179-185, December 2012 ISSN 0031 - 7683 Date Received: 20 Sept 2011 Parchment-Like Paper Using Water Hyacinth Pulp Erlinda L. Mari Forest Products Research and Development Institute Department of Science and Technology College, Laguna Water hyacinth pulps, obtained by open-vessel cooking of fresh, air-dried, and ground water hyacinth stems, were mixed with abaca and wastepaper pulps to form handsheets. The handsheets had natural glaze and those from pure hyacinth pulps were fairly translucent, with Cobb values of 38-40 g/m2 that compare well with commercial parchment paper. Compared with either pure abaca or pure wastepaper pulp, replacement with water hyacinth pulp by 25 to 75% significantly improved burst index and tensile index, suggesting better formation and bonding of fibers. Inversely, however, any amount of the soft and short-fibered hyacinth pulp with either pulp reduced tear index, understandably because this property is dependent more on fiber length. With wastepaper pulp, water hyacinth pulp improves the tensile property to a level comparable with that of paper from abaca pulp as well as parchment paper. Key Words: Cobb values, fiber formation, tensile index INTRODUCTION Interestingly, water hyacinth is already widely used in handmade papermaking (HMP) in Kenya (http:// Local studies on the pulp and papermaking potential of www.unep.org/roa 2008) and Bangladesh (http:// water hyacinth conducted in the late seventies (Zerrudo www.

This material was invented in the UK in the mid-19th century and is widely used 13 because of its excellent characteristics, such as impact resistance and electrical insulation. Recently 14 the matured vulcanized fiber has been recognized as a renewable and biodegradable material and 15 reevaluated with advanced cellulose nanofiber (CNF) technologies. The microscopic analysis based 16 on the improved freeze-drying method revealed that the vulcanized fiber strength can be attributed 17 to the chemically defibrillated cellulose nanofibers. The architecture is similar to a composite made 18 from the same raw material in which the residual cellulose fibers serve as reinforcement, and the 19 nanofibers serve as adhesives. In this report, we describe the history and structural characteristics of 20 vulcanized fibers and introduce a new aspect in zinc chloride treatment of cellulose.

Abstract: Because there is a lack of wood resources in many countries, this work focused on pulp and paper production from the waste and agricultural residues of non-wood plants. The work aimed to pulp the nitrate-alkaline of black mustard (Brassica Nigra L.) and camelina (Camelina Sativa L.). The black mustard and the camelina were selected due to the expanding planted areas of these crops in the Czech Republic. To characterize the chemical composition of black mustard and camelina, cellulose, lignin, ash, and extractives were determined. Raw alpha-cellulose, beta-cellulose, and gamma-cellulose were also measured. The results showed that the content of lignin in non-wood plants is lower than that in softwoods. The cooked pulp was characterized by the delignification degree–Kappa number.
